Commonly Used Options
Certain options require that you reboot the computer for new settings to take effect.
Changing the Boot Sequence
The boot sequence, or boot order, tells the computer where to look to find the software
needed to start the operating system. You can control the boot sequence using the Boot
Order page of the system setup program. The Boot Order page displays a general list of the
bootable devices that may be installed in your computer, including but not limited to the
following:
• Diskette Drive
•Modular bay HDD
•Internal HDD
• CD/DVD/CD-R W d r i v e
During the boot routine, the computer starts at the top of the list and scans each enabled
device for the operating system start-up files. When the computer finds the f iles, it stops
searching and starts the operating system.
To control the boot devices, select (highlight) a device by pressing the or key,
and then enable or disable the device or change its order in the list.

Enabled items appear as white and display a small triangle to their left; disabled items
